别 is used to make a negative command: don’t ...

So in this sentence, it tells someone not to waste something.

A very common pattern is:

别 + verb

For example:

• 别说话。 = Don’t talk.
• 别走。 = Don’t go.
• 别浪费。 = Don’t waste.

It is one of the most common ways to say don’t in spoken Mandarin.

In Mandarin, the subject is often omitted when it is obvious from context.

Commands very often leave out 你:

• 别浪费完好的生活用品。 instead of
• 你别浪费完好的生活用品。

Both are possible, but leaving out 你 sounds more natural in many situations.

So the sentence still means Don’t waste ..., with you understood.

Both can mean don’t, but there is a nuance:

• 别 is very common in speech and is short and direct.
• 不要 can also mean don’t, but it can sound a little fuller, and in other contexts it can also mean do not want.

Compare:

• 别浪费。 = Don’t waste.
• 不要浪费。 = Don’t waste.

In this sentence, 别 is completely natural.

Yes. In this sentence, 浪费 is a verb meaning to waste.

Structure:

• 别 = don’t
• 浪费 = waste
• 完好的生活用品 = intact / perfectly usable household items

So 浪费 takes an object here.

You can see the same pattern in:

• 别浪费时间。 = Don’t waste time.
• 别浪费水。 = Don’t waste water.
• 别浪费食物。 = Don’t waste food.

完好 means something like:

• intact
• undamaged
• in good condition
• still perfectly usable

It does not just mean complete in an abstract sense. It usually suggests that the item has not been broken or damaged.

So 完好的生活用品 means household/daily-use items that are still in good condition.

Here, 的 links the descriptive word 完好 to the noun 生活用品.

So:

• 完好 = intact / in good condition
• 的 = linking particle
• 生活用品 = household items / daily-use items

Together: 完好的生活用品 = household items that are in good condition

In Mandarin, when an adjective or descriptive phrase modifies a noun, 的 is often used.

Especially with a two-syllable adjective like 完好, using 的 sounds natural.

Usually, you would keep 的 here.

With some very short and common adjective+noun combinations, Mandarin can omit 的, especially with monosyllabic adjectives:

• 好人
• 大房子
• 新车

But 完好生活用品 would sound unnatural.
So 完好的生活用品 is the correct natural form.

生活用品 is a compound noun:

• 生活 = life / daily life
• 用品 = articles for use / items for use

Together, it means daily necessities, household items, or everyday-use items, depending on context.

Examples might include:

• clothes
• containers
• tools
• toiletries
• basic household goods

It is a fairly broad term.

This is normal Mandarin word order.

The basic pattern is:

别 + verb + object

So:

• 别 = don’t
• 浪费 = waste
• 完好的生活用品 = the object

Inside the object, the modifier comes before the noun:

• 完好的 modifies 生活用品

So the sentence is built very regularly:

1. negative command
2. action
3. thing being acted on

Yes, but it sounds a bit formal or like a notice/slogan/public message.

That is because:

• 生活用品 is a fairly formal noun
• 完好 is also somewhat formal

In everyday speech, people might say something more conversational, such as:

• 别浪费还能用的东西。 = Don’t waste things that can still be used.
• 别把好好的生活用品扔了。 = Don’t throw away perfectly good household items.

So the given sentence is natural, but it feels more like written guidance, a sign, or a campaign message than casual chat.

Yes.

It can describe the condition of something on its own, often after a noun:

• 东西完好。 = The thing is intact.
• 包装完好。 = The packaging is intact.
• 机器完好无损。 = The machine is completely undamaged.

In your sentence, though, it is being used before a noun with 的:

• 完好的生活用品

So both uses are possible:

• predicative use: 这个箱子完好。
• attributive use: 完好的箱子

Literally, it means don’t waste.

But in context, especially with 完好的生活用品, it may strongly imply:

• don’t throw away usable items
• don’t discard things that are still in good condition

So 浪费 is broader than just throw away. It means using something carelessly or letting it go to waste. In real situations, that can include throwing it away, but the core meaning is still waste.
